US 10,122,361 B2 · Electronic device and associated signal processing method

Abstract

An electronic device includes a transmission interface, a driving circuit, a receiving circuit, a sampling circuit, a detecting circuit, a timing control circuit and a processing circuit. The transmission interface is for connecting to another electronic device via a connecting cable. The driving circuit outputs a backward signal via the transmission interface to the another electronic device. The receiving circuit receives a received signal including the backward signal and a forward signal from the transmission interface. The sampling circuit samples the received signal to obtain a plurality of sample results. The detecting circuit detects transitions of the sample results to obtain a plurality of detection results. The processing circuit generates a control signal according to the detection results, and adjusts a time point at which the driving circuit outputs the backward signal through the timing control circuit.
